$A$ susceptibility of a certain magnetic material is $ 400 $. What is the class of the magnetic material $ ? $

Which of the following statements are correct?
$(A)$ Electric monopoles do not exist whereas magnetic monopoles exist.
$(B)$ Magnetic field lines due to a solenoid at its ends and outside cannot be completely straight and confined.
$(C)$ Magnetic field lines are completely confined within a toroid.
$(D)$ Magnetic field lines inside a bar magnet are not parallel.
$(E)$ $\chi = -1$ is the condition for a perfect diamagnetic material,where $\chi$ is its magnetic susceptibility.
Choose the correct answer from the options given below:

Above the Curie temperature,the susceptibility of a ferromagnetic substance varies

The resultant force acting on a diamagnetic material in a non-uniform magnetic field is in the direction . . . . . . .

Curie temperature is the temperature above which

The magnetic susceptibility is negative for
